In air-conditioning systems, streams of cold and warm air are mixed to get air with the right temperature. Consider a mixing chamber into which cold air enters at 8C and 100 kPa at a rate of 0.55 m^3 /s and warm air enters at 300C and 100 kPa. The ratio of mass flow rates of warm to cold air streams is 1.6. Using variable specific heats, determine the mixture temperature leaving the mixing chamber.
